Today we continued our efforts on getting the Enginator is tip-top operating shape (Warren Newhauser/Chuck Trabert), reattaching wood ceiling in the instrument room (Chuck Trabert) and fitting new wooden stanchions (Buzz Morissette).
We first adjusted oil pressure on Enginator to the 30psi recommended down from above 40psi. Too high of oil pressure will ruin the oil pressure sensor.
Chuck and I attempted replacement of fan belt, but new belt was wrong size. We ended up cutting new belt off ($10 loss) to get it out from behind fan quicker. Chuck measured the old belt and we need 5L350 not 5L300. We can definitely see why later model Waukesha engines had a better fan belt arrangement – they could not afford two guys 1/2 hr for a belt replacement.
Changed the oil filter with a new Baldwin P67 cartridge filter which I ordered online from Application Associates. We will change oil every 30 years whether it needs it or not!
Verified the oil pressure sensor will trip the engine if the pressure is below 5psi per specs.
Removed and tested the engine temp sensor to verify it will shut down the engine in case of overheating. The mechanical mechanism to short out the circuit when overheating is detected may have been stuck. I moved it with a screwdriver, re-installed old sensor unit and installed new crimp connectors on the cable to it, but at the end of the work day they seem to be shorted out inside the protective metal housing they are contained in.
Verified the the Oil-Heat thermal time delay trip is working properly to shut the engine down if oil pressure or engine temp exceeds limits.
Chuck screwed several severely sagging ceiling boards back to the wooded staunchens in the ceiling. Reattached the overhead light fixture in the instrument room. We concluded that the boards have slightly expanded in length due to contact with water and popped out. Need to make a saw cut in them and they will lay flat on the ceiling.
Buzz Morisette fitted the new wooded staunchens he’s been cutting in the wood shop for the instrument room.
All in all, a very productive day!
